which condition precludes the replacement.

of the wires as theybreak in service, due to m the continued abrasiveeffect of the threads passingtherethough. In addition, mill nuts or likedevices are often required to hold the membersin place onthe spindles.lVhere' self-contained springs held in place by bushingshave been used,the'disadvantage of the mill nut has been obviated but the re-wiring Vof such devices is,.in every instance, a custom job. Where devices ofthe type shown in the patent to H. E. Herr #1,61l,552 have been. used,considerable difficulty has been experienced with the maintenance andrepair of these devices, due'to the fact that special tools. arerequired for the assembling steps,

in order to remove broken wires and replace them with new Ones, and inaddltion, the

expansion anchoring sleeves frequently break andcannotbe re placed, thusrequiring'scrapping of the entire unit.

It is an object of'the present invention to provide a fiyerfor-spinningpurposeswhich is composed of a plurality of replaceableparts;

It is scribed which is freelymovable and provided with replaceable.parts throughout.

Yet another'objectxof this invention is the provision of a novel flyerconstruction in whicht-heilyerwires or arms serve as a lock- 7 4o ingmeans. 7

As shown in my application Serial No. 458,210 (Case A) filed May 31,1980, flyer wires are subject to relatively frequent replacementdue tothe wearing out of the eyes by the abrasive action of the threadspassing therethrough. In my above identified" application, I have shownone form of a flyer device provided with replaceable parts and oneinwhich the entire construction may be readily dismounted andreassembled'in. place on the machine at low cost and without requiringthe shipment of the fiyers to separate points for replacement of theflyer wires.

In the drawings there is shown the usual. bobbin 1v mounted on spindleQl with flyer block 3 and flyer wires 4 secured thereto. The flyer wiresare provided with the usual eyelets 5, which as indicated in myapplication Ser. No. 458,210 filed May 31, 1930 (Case A). I are providedwith. abrasion resistant metal. :13 While abrasion resistant metal maybe used it will of course be appreciated that mineral substances such asagate and the like-may be made use of.

In the present invention, the flyer block 3 2T0 comprises an upperportion 6 having a central aperture 7 and internal female thread 8 and ashoulder portion 9 together with a bot tom edge portion 10. The latterportion may be serrated as indicated in Fig. 4 for a purpose to bedescribed more in detail hereinafter. The lower portion 11 of member 8is provided with a central aperture 12 registering with aperture 7 ofmember 6 and is also provided with an annular channel or flange 13adapted to receive the member of the upper portion of the flyer block.In addition, the member 11 is provided with a central portion 14 havinga thread 15 formed thereon and adapted to engage a corresponding thread8 in member 6. At its bottom or outer part, member 11 is provided withan internally extending shoulder portion 16 adapted to provide a supportfor the spring member 17. IVhen members 6 and 11 are screwed together,the spring member 17 having been at first inserted within the centralaperture of member 11, the spring will be held in position by theshoulders 9 and 16 of the cooperating members.

The flyer wires 4 are provided with the usual central curve portion 20-and lateral extending portions 21 adapted to engage apertures or slots22 in section 13 of member 11. Section 20 of the flyer wires is bowedupwardly as indicated at 23 topermit a firm gripping thereof by serratedsection 10 .of member 6 when the flyer wire has been inserted inposition and member 6 screwed up on member 11. i

It will readily be seen that the improved flyer block of the presentconstruction may be easily assembled and disassembled and worn partsreplaced by other like parts without re quiring the scrapping of anentire unit. In addition, one or more flyer wires may be made use of,the necessary tension being obtained by providing any desired angularityabout the apertures 22 and the adjoining portions 24 of sections 13.

In operation, the spindle 2 will be directly engaged by the springmember 17 which may have any desired configuration or construction, acoil spring being shown here by way of example only, the said spindleengaging spring or coil being freely movable in its journal formed bythe pill box construction of the abutting parts of the flyer block.While a serrated engaging portion 10 has been disclosed it will ofcourse be appreciated that good results may be obtained by the use of asmooth surface but a serrated edge such as the one disclosed providesbetter locking for parts which are normally subjected to vibrationstresses. I

In accordance with the provisions of the patent statutes, I havedescribed the principles of operation of my invention, together with'thedevice which I now consider to represent a preferred embodiment thereof;but

I desire to have it understood that the device shown is onlyillustrative of the basic concept of the present invention, and that thesaid invention may be carried out by other means.
